Yes, you can link multiple Instagram accounts to your Facebook profile. When you link an Instagram account to Facebook, your Facebook friends who are on Instagram may get a notification telling them that you're using that Instagram account.

You can change the name of the Facebook album you upload Instagram posts to by going to the photo album on Facebook.

Keep in mind that if you change the name of the Facebook album, the next time you share an Instagram post to Facebook a new album titled Instagram Photos will be automatically created, and your post will be added there.

To share a photo you've previously uploaded on Instagram to another site:

Go to your profile and tap the post you'd like to share.

Tap Share.

Tap the name of the site where you'd like to share your post (Facebook, Twitter or Tumblr) and then tap Share. You can also choose Email or Copy Link.

Keep in mind that if you haven't previously linked your Instagram account to that site or service, you'll be prompted to log in. Once you've linked your Instagram account to that account, the icon for that site will turn blue.

Hipstamatic

When using Hipstamatic, you can share your photo directly to Instagram. Just choose to share the photo and then tap the Instagram icon. You can write a caption for your photo and also decide whether you want Hipstamatic to automatically include the #hipstamatic hashtag as well as tags noting which camera and lens you used to take the photo.

After you link your Instagram account to Hipstamatic and choose to share, your photo will automatically appear on Instagram. If tags are turned on for your photo, Hipstamatic automatically includes tags in the caption. An attribution ("Taken with Hipstamatic") will appear below your caption. Tapping on "Hipstamatic" will direct you to the app if it's already installed on your phone or to the Hipstamatic App Store page if you haven't installed it yet.

Log into your account.

Confirm the app's permissions.

Tap the Mixi icon to turn sharing on. Your photo will now upload to Instagram and Mixi.
